MICHAEL C. MURPHY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO A. G.SPALDING & BROS. MANFG. 00., A CORPORATION OF MASSACHUSETTS.

ATHLETIC PUTTING-SHOT.

To all whom it may concern:

Be it known that I, MICHAEL C. MURPHY, citizen of the United States,residing at Philadelphia, Pennsylvania, have invented certain new anduseful Improvements in Athletic Putting-Shots, of which the following isa specification.

It is the object of my invention to provide a putting shot of therequired weight but of small diameter, which will not be subject tochipping or bruising, the said shot consisting broadly of a lead ballwithin a shell of iron or steel which will resist the wear and shock towhich such implements are subjected, the lead furnishing approximatelythe entire weight necessary and the iron shell the durable shockandwearresisting covering therefor. Heretofore, so far as I am aware, theseshots have been made of a solid ball of iron or a solid ball of leadfrom twelve to sixteen pounds in weight. It is desirable to get theweight in as small a compass or diameter as possible, and hence the shotcomposed of lead has heretofore been preferred. These shots, however,must be maintained of accurate weight, but this is not possible with alead shot, for in use the lead shot is apt to become chipped or damagedto an extent where it shows a loss in weight, and if the shot putteruses such an implement of this kind in any event, he will bedisqualified if, after making a record, the shot is weighed and foundwanting in this particular, and this may occur also even if the shot,when thrown, is of full weight, but because of chipping when it strikes,weight is lost.

In carrying out my invent-ion I aim to provide a shot of compact formcomposed mainly of lead, protected by a shock re-. sisting shellcomposed preferably of iron. In making the shot a hollow iron sphere isemployed having an opening at one point through which hot lead may bepoured. The iron shell is in the form of a casting, and has on itsinterior a number of teeth or spikes projecting radially inward, andabout these spikes the lead filling is molded so that the spikes willengage the same and thereby prevent the lead interior from shift-Specification of Letters Patent.

ing or moving in relation to the iron shell. I do not limit myself,however, to having these spikes projecting radially, as it is simplynecessary for them to project inwardly in relation to the iron shell soas to engage the lead filling and hold the same agalnst movement.

In the accompanying drawing, I show a sectional View through a puttingshot of the character described, in which 1 is the iron shell, 2 thelead filling, 3 the inwardly projecting spike or spikes, and 4: theopening through which the lead is poured.

While I have described my invention in connection with a putting shot, Ido not limit myself in this respect, as the invention may be embodied inother forms of putting implements besides that of a shot, nor do I limitmyself to the use of spikes on the interior of the shell, as other meansmay be provided to engage the lead interior to prevent shifting thereof.

In order to present a smooth exterior surface to the shot, I close theopening through which the lead or other heavy material is introduced orpoured so that the surface of this plug will be flush with the exteriorperiphery of the ball. I prefer to effect this closing of the openingand to bring the exposed surface at this point flush with the exteriorsurface of the ball by pouring sufficient lead into the ball so that itwill overflow at the opening, and when this cools this lead plug isfiled off flush.

I claim as my invention:

1. In a putting shot or the like, a hollow shell of shockandwear-resisting material having its interior filled with a material ofgreater specific gravity, said shell having means on its interior toprevent shifting of the filling material, substantially as described.

2. In a putting shot or the like, a hollow shell of shockandWear-resisting material having its interior filled with a material ofgreater specific gravity, said shell having means on its interior toprevent shifting of the filling material, said means consisting of aninwardly projecting spike or spikes engaging the filling material.

8. A putting shot consisting of a hollow In testimony whereof, I afiixmy signature spherical shell formed of one piece of unin presence of twoWitnesses.
